A mother's tragic diagnosis. A daughter's life on hold. An ending and a new beginning ... Cassandra McDowall's mother has been forgetful for a while, but she never anticipated rapid-onset Alzheimer's to come out of nowhere and shake their world to its very core. As Cassie puts her already-lackluster life on hold, her mom's indomitable will and spirit of adventure prove to be a handful. And as her mother fades, the two embark on one last adventure-a journey that reveals secrets on the brink of being lost, the joy of foreign sunsets, and love where she hadn't thought it possible.
